Hacking group Shadow Brokers has released the password to a trove of NSA exploits in what they say is a form of protest against President Donald Trump for going back on his campaign promises, and warning the president, “Don’t forget your base.”

The shadowy group first emerged last August and released hacking exploits used by the NSA’s Equation Group, which included vulnerabilities in firewall products, and a list of IP addresses the NSA had exploited, which the group released at a later date.

Shadow Brokers released passwords to the rest of the exploits on Saturday, in a move they described as a protest against Trump, who they say has “abandoned” his base by going back on many promises made on the campaign trail.

Bitter lesson:
When any government conceals knowledge of vulnerabilities in common software, those vulns will be found and used by enemies. https://t.co/EfLgJMwbNs

The password provided by Shadow Brokers unlocks the hacking tools, which include servers belonging to companies and universities which are allegedly used to deploy malware, according to researchers who have examined some of the documents. WikiLeaks tweeted the dump includes “hacking attacks on EU states, Russia, China, Japan and South East Asia.”

The group also criticized Trump for launching the cruise missile strike against Syria, saying: “Whose war are you fighting? Israeli Nationalists’ (Zionist) and Goldman Sachs’ war? Chinese Globalists’ and Goldman Sachs war? Is not looking like you fighting the domestic wars, the movement elected you to be fighting.”

The group earlier attempted to auction the “best files” for more 1 million Bitcoin, but abandoned the plan in January.

The post seemingly lends clues as to the identity of the group. “Did you know most of the shadow brokers’ members have taken the oath ‘…to protect and defend the constitution of the United States against all enemies foreign and domestic…’.” it reads. “Yes sir! Most of us used to be The Deep State everyone is talking about.”

While the Shadow Brokers were accused of being Russians, several NSA insiders earlier told the media that signs pointed to it being someone within the NSA.
